I'm looking for recommendations on a computer-controlled
multimeter to automate a test procedure. I'd like to be
able to have the computer select voltage, resistance, etc.,
choose various ranges in each, and transmit readings to a
PC.

I see a lot of units that communicate, but I'm unclear
whether they allow functions and ranges to be set, or
whether they just transmit results from the range selected
on the front dial.

The one unusual requirement is a high resistance range (e.g.
2000Mohm). ACV/DCV/ohms ranges can otherwise be similar to
regular handheld units.

Any suggestions?
